HER2 status not consistent
I got the HER2, ER, PR status of BRCA patients from the BRCA TCGA publication supplementary:
https://www.nature.com/articles/nature11412#supplementary-information
filename: TCGA_Supplementary Tables 1-4.csv
column: HER2_Final_Status
But since it is from 2012, after some months, I downloaded the newer clinical data from cbioportal**:
http://www.cbioportal.org/study?id=brca_tcga#clinical
filename: data_bcr_clinical_data_patient.txt
columns: IHC-Status, HER2 fish status
However, I noticed that hundreds patients had different her2 status then they had in the old tcga publication:
Barcode IHC-status(cbioportal) Her2 fish status (cbioportal) HER2_Final_Status(tcga publication)
TCGA-A1-A0SH Equivocal Negative Negative
TCGA-A2-A04U Negative Positive Negative
TCGA-A2-A0T2 Negative Not Evaluated Negative
TCGA-A8-A06R Positive Positive Equivocal
At first, I thought there is a method to convert both ihc and fish statuses into one (final status). But I failed to find such method.
In TCGA-A1-A0SH, it seems Fish is prefered.
In TCGA-A2-A04U , it seems it is IHC.
in TCGA-A8-A06R it is neither.
**I verified that for those 4 patients, her2 status is consistent between cbioportal and current TCGA clinical files. (her2_fish_status, her2_status_by_ihc in clinical files)
Thanks in advance,
Maor

Unable to find BAM file index
When I try to run `samtools mpileup` it expects to find the BAM index in the same folder as the BAM file with the extension ".bai". I'm not sure how I can expose the BAM index to a tool that assumes a certain file location for the index.

Expression of long non-coding RNAs
Hi!
Which is the best way to get access to the expression of long non-coding RNAs? Is there any processed data (I have already checked on the case explorer) or I should reanalyze the raw data using something like Cufflinks?

SVS files are unavailable through the APi
SVS files are availble through the website:
https://portal.gdc.cancer.gov/cases/9fe336a8-08a7-4fe7-bf45-afd6a8eb9c75
They are also available on the data portal as of May 21 2018:
(same page, click on Files, it leads to data portal. You can see svs files for this case)
However issue an API call to:
https://cgc-datasets-api.sbgenomics.com/datasets/v0/tcga/cases/9FE336A8-08A7-4FE7-BF45-AFD6A8EB9C75/files
No svs files are available.

Get diagnosis data
Hi!
I'm trying to download the diagnosis data to see if I can find some correlations with my gene of interest.
In the Data browser I can see the Diagnosis Details but despite making subgroups for the data import I can't get those details in the metadata file. Is there any way to extract them?
Thanks

I can't add TCGA data from a query to my project
I've joined today as a beta user and started a project, but once I do a query and pull up a list of files, I'm unable to highlight them either on the query map or the list of files in order to add them to my project for analysis. Is this a bug or am I doing something wrong? The help page indicates that I should be able to click on a path to highlight and add those files. Thanks!

Multiple TCGA BAM for same sample
HI there,
I've noticed that some TCGA samples have multiple RNA-Seq BAM files, what would be the difference between the files?
If it's convenient to use one over the other, what criteria should be used to select such file.
Example:
TCGA-STAD RNA-seq
TCGA-BR-8368-01A-11R-2343-13_rnaseq.bam 14.5GB
_1_TCGA-BR-8368-01A-11R-2343-13_rnaseq.bam 14.7GB
Thanks,
Franco
